With only seven US guilds and thirty-seven guilds killing Ragnaros on heroic mode in 25-man, it was inevitable that Ragnaros would get a nerf. The fight was hard and many guilds three healed it for their kill, mine included.

Tonight, the nerfbat finally landed. Mid-attempt for many, Ragnaros' health was reduced--it's a fight based on health percentages for phase transitions, so this will reduce the second phase probably by an entire seed phase, greatly reducing the encounter's difficulty. Additionally, phase four--the heroic mode phase--allows Ragnaros to heal up for 50% of his health. With his overall health changed this much, it means he'll heal up for a lot less.

On heroic mode, Ragnaros now has 74.2 million on 10-man; on 25-man, it's now 246.9 million from its previous 290 million.

Prenerf Kill Statistics

Taken from Wowprogress, here are the statistics prenerf for kills in Firelands. Expect them to change drastically this week.

We got a chance to check out Ragnaros yesterday on 10-man normal mode. Seeing a final boss for an instance on the PTR is a rare treat; Blizzard usually doesn't give away the end of the instance so easily and it was surprisingly polished except for a minor glitch with visuals on the platform.

As you might remember from the dungeon journal entry, Ragnaros is a three phase fight in normal mode. There's an additional fourth phase in heroic. We were able to get him down into phase three and close to a kill. He seemed a little undertuned, even if it was 10-man normal mode and it is PTR. It was just too easy to get down quickly. This was largely because few abilities were punishing--it was only in phase three and during intermissions which served as phase transition that you could wipe from a single mistake.

We made a quick video to show you the footage of our progress (special thanks to my guild Out of Line for being awesome and helping). This video is a rough guide and hopefully will give you a better overview of the fight's general progression. Of course, if you prefer text, there's also a write-up after the break.

The PTR updated this weekend with the encounter journal. The developers at Wowhead have been working on integrating it into our database entries and it's an exciting feature you should see soon. However, in this case, soon isn't enough: you probably want to see it right now. Well, you can! With the help of volunteers ArgentSun, Perculia, and Remnath, I've transcribed the data you care about--!

Below are the encounter journals for all seven bosses in the zone (plus Occu'thar in Baradin Hold), so tread lightly if spoilers scare you. Of course, if you're into seeing what you'll be facing on 4.2, go and indulge yourself. It's worth it. Ragnaros is the best looking fight in particular; it's epic on a level that Alone in the Darkness (25 player) was in Ulduar and quite similar in design, too. During the fight on heroic mode, you will face an additional stage in which you will be aided by three familiar friends: Cenarius, Arch Druid Hamuul Runetotem, and Malfurion Stormrage. It sounds a lot like the Keepers in Ulduar.

Anyway, if these journals are any indication, this dungeon should cure a lot of burnout players have been facing. And hey, who knows, maybe those ~600,000 subscribers Blizzard "lost" will come back on patch day!

Beth'tilac

Matriach of the Cinderweb Brood, Beth'tilac and her merciless offspring sate their appetites by sucking the magma and fire from the corpses of elementals.

Lord Rhyolith

Stage 2: Liquid Form

Alysrazor

Shannox

The flamewakers are among the most feared elemental guardians in the Firelands. Shannox is no exception. Serving as the chief hunter and kennel master of Ragnaros's hell hounds, Shannox patrols the elemental realm with his two most ferocious beats: Riplimb and Rageface.

Boss Abilities

Riplimb will then break off from combat, fetch the spear, and return it to Shannox.

: When both of Shannox's hounds are defeated, he goes into a frenzy, increasing physical damage and attack speed by 30%. Shannox no longer uses Hurl Spear after this point, and instead drives his spear directly into the ground to trigger the same cascade of molten eruptions around the impact point, which deal 52,530 Fire damage to enemies that stand in them.

Baleroc, the Gatekeeper

Baleroc earned a reputation as a merciless combatant during the elemental wars of ancient Azeroth. Now that he is confined to the Firelands, Baleroc's sanity has dwindled. Few elementals dare disturb him, fearful that they will become victim to his battlelust.

Boss Abilities

: If there are no players within 15 yards of a Shard of Torment, the Shard pulses this effect, dealing 15000 Shadow damage each second to all players.

: If a player casts a direct heal on someone who is being damaged by Torment, the healer gains an application of Vital Spark for each stack of Torment on the target.

: Increases healing done by targets affected by Blaze of Glory by 2% per stack of Vital Spark consumed to create this effect, lasting 15 sec. When Vital Flame expires, it restores the Vital Spark stacks that were consumed to create the effect.

Blades of BalerocBaleroc will periodically empower one of his blades with Shadow or Fire energy and wield it alone for 15 sec.

: Baleroc's melee strikes deal Shadow damage equal to 90% of the target's maximum health, instead of their normal physical damage. This damage cannot be resisted or mitigated by normal means. The time between Baleroc's attacks is increased by 100% while this effect is active.

: Baleroc's melee strikes deal 80000 Fire damage to the target instead of their normal physical damage while this effect is active.

Majordomo Staghelm

The loss of his son, Valstann, in the War of the Shifting Sands utterly shattered Fandral Staghelm's spirit. Now empowered by Ragnaros as the new Majordomo of the Firelands (replacing the deceased Majordomo Executus) and the leader of the treacherous Druids of the Flame, Fandral seeks to bring ruin to Azeroth rather than live in a world without his beloved child.
